Problems solved by technology

[0004] At present, a variety of green feed additives have been developed on the market. The inventors found that the existing feed additives for pigs are not very suitable for lactating sows.
On the one hand, the existing feed additives for pigs are added in a large amount, which is irritating to the esophagus and gastrointestinal mucosa of lactating sows, and the conditioning ability of lactating sows is not ideal, and cannot promote the development of mammary glands, and cannot make lactating sows Pigs maintain an ideal lactation level; on the other hand, the existing feed additives for pigs cannot play a role through sow milk to enhance the physical fitness of piglets

Abstract

The invention provides a feed additive for lactating sows and a preparation method thereof, and belongs to the field of feed additives. The feed additive for lactating sows is prepared from the following raw materials in parts by weight: 30-40 parts of compound amino acid, 3-7 parts of compound enzyme, 20-30 parts of a synergist, 1-3 parts of microcrystalline cellulose, 3-5 parts of a dandelion extract, 10-15 parts of formic acid, 1-3 parts of soy isoflavone, 5-10 parts of rice bran powder and 10-15 parts of black soybean hull powder. The feed additive disclosed by the invention is added into pig feed according to the addition amount of 3wt%, and the daily lactation capacity of lactating sows can reach 6.97-7.13 kg; the weaning survival rate of the piglets in 24 days can reach 96.1-97.2%, and the average weaning weight gain rate of the piglets in 24 days can reach 401-423%.

Description

technical field [0001] The invention relates to the field of feed additives, in particular to a feed additive for suckling sows and a preparation method thereof. Background technique [0002] Feed additives refer to small or trace amounts of substances added during the production, processing and use of feeds. They are used in small amounts in feeds, but can often play a significant role. Feed additives are inevitable raw materials used in the modern feed industry. They have obvious effects on strengthening the nutritional value of basic feeds, improving animal production performance, ensuring animal health, saving feed costs, and improving the quality of animal products. [0003] In the prior art, for the composition of feed additives for pigs, formic acid, acetic acid, propionic acid, citric acid, etc. are often preferred in the industry, and then combined with other synergistic components, such as medium-chain fatty acids, monoglycerides, amino acids, bacterial agents, etc...
